    The microphone tracking is a great idea and seems well implemented, but there are two issues that baffle me that are easily fixed: 1) I often wake up early and want to know if I've gotten enough sleep. Show me. Why make me remember what time I went to bed and calculate? 2) It knows when I'm awake or asleep based on the microphone data so why doesn't it subtract out the time I was not sleeping? "In bed" time should be a second, less-important metric. Time actually asleep is more important.

    sleep cycle sleep analysis & smart alarm clock Ever since the new Android update in late September 2020 (Android version 11 I believe) it no longer records my sleep movements. I've tried cleaning my microphone, using the accelerometer, and updating the app. Since the whole reason I used this was to wake up at the end of a sleep cycle, it's pretty much useless now. It was great when it worked.

    Since I started using this app I can't even think of going back to using a regular alarm. It completely transformed my mornings. It takes time for the app to study your sleep cycle and it woke me up from deep sleep more than once or twice. It also drains the battery if the phone is not connected to the power source which is a bummer since it's really not healthy to charge the phone next to your head when you sleep.

    I had this app for iPhone and paid for it and when I switched to android they wouldn't honor my account, and now they are taking away the one reason I use the app in the first place and putting it behind not just a pay wall but a subscription based one to boot. You expect me to pay you again for this? Bye. There are plenty of other apps out there.

    Better than a regular old alarm, been using this for a while and its really insightful to be able to see statistics about your sleeping habits. I paid for further access but would like to see new content being produced in terms of sounds, its been the same since i've installed it and I feel like the variations help a lot to make falling asleep more fun, so new sounds would be greatly appreciated. 👍

    It's great but I sleep in the same bed as my wife and two dogs. It appears to pick up their movement and noise at night/morning which adversely impacts my "wake-up" time. I can't imagine the app's premium features fix this issue so I have a hard time recommending this app to anyone, let alone purchase it myself.

  7. Josef H.-avatar

    Josef H.


    It's not a bad app at all but in order to access statistics and other features, you need to pay hundreds of euro, depending on how many years you're going to use the app for. They ask for 30 euro every single year, so the app is never yours. I call this greediness. Sleep As Android is a much better option. You pay and it's yours forever.

    I love the idea of this app, and in the first time I used it, it was the best nights sleep I've had in a long time! But over time I've started to tire of the alarm (even though it's really nice!) And the free version o it has three sounds...

    Does not work for sleep tracking, it said I slept 7hr 11 min when I definitely got less ; I woke up several times that night. It literally just tracks the time you put in you start sleeping to when your alarm goes off no measurement beyond that

    When I started to use the app it worked great. Woke me up in the right time, I was get out of bed easily. But recently it doesn't do the job, always wakes me up in the middle of a dream. Hope they will fix it.

    I'd give this app more stars however after registering for premium I'm unable to create an account due to consistent network errors and I've tried both using my data connection and my home Wi-Fi

    Summary: After 1 week trial period, it has potential but doesn't work right for people who have trouble sleeping, and the useful features are too expensive. Details: I have severe leg cramps that make it difficult for me to fall asleep at night. I thought I'd try this app because (with the paid features) you can enter activities or other things you do during the day and it analyzes whether those things help or hinder your sleep for you. Three out of the six nights were absolutely torture because I couldn't fall asleep for hours or woke up for over an hour due to leg pain. I felt awful when I had to get up. However, the app said those were my best night's sleep, likely because I "went to bed" and got up at around the same time each of those nights. On the other hand, two nights I didn't go to bed until much later and let myself sleep in an hour or two later because of going to bed late. It was wonderful because I was able to fall asleep quickly and I felt much better when I woke up than those other nights! However, the app gave these nights my lowest sleep scores. Regularity is important, but these sleep score results are exactly opposite what my mind and mood were telling me the next day. I don't think the app places enough emphasis at all on actual sleep vs going to bed and getting up at the same time. If it was like $5 I'd be willing to keep trying to see if it learns better because I like the idea of the sleep notes (IF the results were accurate), but $30 every year is much too expensive for what I've experienced so far.

    I always wake up before the end of the cycle but it's great to see what I'm doing in the night. I always suspected I was waking up multiple times in this app shows that I am.

  14. xTheCooieSaysNox-avatar



    This app is a joke! the sleep leaves are the same as the display on here the app store! It's just a alarms, if you want everything else you have to pay for it!

    This app really helped me see what my sleep pattern is and I had no idea how much of a light sleeper i was until i got this app. If you are looking through the reviews to find out if its worth it...I deffinetly recommend it but there are some in-app purchases like the sleep notes and a few other things. I didn't think it was worth that much just so I could see some statistics so I did not get those features. Also, the alarm 100% still works on the app if your phone turns off but not shut down :)

    First Time (1 night review). It has managed to record my sleeping pattern reasonably well, and I have discovered I might snore with the recordings as proof, but I feel that could have been my mum or her partner in the next room as they snore all the time. Not sure, if the recorder would pick up their snoring. I'm also not sure if the recorder would pick up sounds from my mum's partner getting ready for work at 4am or outside construction work at 8am etc. I'll give this week a trial run!

  17. Codzilla2323-avatar



    Don't waste your time. $39.99 pet year. Your don't get much information without handing over your card details. Then you can trial for free for 7 days. On day 4 it asks me to rate this app??. How can you rate it, when it gives you nothing.!!! The app says wait 5 days for info to be revealed. Then you have to hand over your card details.

    I purchased this app years ago and have been using it consistently on every device I've owned. Now I'm being told in the app that my "free" version ends soon and I'll have to pay a subscription, when I've already paid for the app. When it prompts me to pay for the subscription I will probably uninstall and will have to look for an alternative.

  19. Claire Murray-avatar

    Claire Murray


    Not accurate, it didn't register any awake time or my husbands snoring! Waste of time, get yourself a fitness tracker with a sleep tracker built in. You can't get data until it has registered so many nights and you can't do so many nights unless you pay. It just tries to hook you into paying with promises of better performance- but doesn't follow through

    I like it . It makes me think about how much sleep, what kind of sleep I get and what causes me not get good sleep and what does. Because I take care of my 2 grandchildren and sister-in-law with Alzheimer's my scheduleI changes. I help with virtual school due to the covid crisis. I have to be there by 5:00 I'm up by 4:00, then I also watch the baby the rest of the time

  22. Philippe Addor-avatar

    Philippe Addor


    Pretty impressive how just with the microphone on the bedside table this app is able to determine my sleep quality. In fact, I still hardly believe that this can work. But it seems it is! What I miss is a feature that records me speaking at night. Since it can record snoring, it should also record "dream chatter".

  23. Mirjam de Vries-avatar

    Mirjam de Vries


    It happens too often that the app "forgets" to actually go off, and I wake up at 7.30 to check the screen where it says "alarm between 6 and 6.30", and starts ringing only when I actually check it myself. Kind of a big problem if you rely on the app for important things like not missing your morning flight.

  24. Isaac Noel-avatar

    Only been using the app for 2 days, cool to see the graph. I'm just wondering, I sleep with headphones on and use a YouTube dark screen rain video to sleep, is there any setting now or maybe in development that will allow the YouTube video to continue playing while it tries to wake you up within the 30 minute period, I noticed it goes into the app directly instead of a prompt that pop ups which would be a lot nicer cause then I could actually use the feature properly. Thanks.

    Let's you see the phases of your sleep and snoring too. Pity the free app offers only the bare minimum of functionality. All the rest is premium

  26. Caitlin Kaczowka-avatar

    Caitlin Kaczowka


    I like the "wake up between" feature, because it's a more gentle version of a snooze button but works more effectively. As for sleep monitoring, it's mediocre... I wake up a lot in the night - I know I do as I see the clock - 2, 3, 4, 5am. I must not be very restless when I do wake up, because the app always show me as sleeping through those times (although in a light sleep) and that I'm getting 90% sleeps every night. I wish you could edit the recording and indicate when you've knowingly woken up. I was hoping to use this app as as starting point for evidence to bring to my doctor for more in-depth investigation since I'm always exhausted.

    I seriously love this app. It's helped me see if I'm actually resting and I love to see how accurate it is! Thank you so much. - update AUG 13 I don't know why, today the app wouldn't record. It took me forever to fix it. ( I still don't know what was wrong). Then I thought maybe it was the app, I uninstalled it and lost a 90 day free trial you guys gave me because of it but it didn't fix the problem.

    I've used this app previously & really liked it but I downloaded the new app this week & the free version is pretty useless. I really don't care for all the bells & whistles, the stories, the sleep aids, the alarm clock. I just want charts & graphs over a longer period and can't justify spending all that money for a premium subscription bundled with features I don't want or need. I'd be happy spending a smaller amount for a premium subscription that meets my needs. Maybe a silver subscription?

  29. Joseph Brown-avatar

    Joseph Brown


    Thanks for the response. Now that I am aware that it won't auto roll into a paid subscription I don't view it as a sneaky design. Just challenging when sleepy. I did not want to start free trial. Screen came up and I thought I dismissed it but I was sleepy and now I have a free trial that I can't stop. 89 days until I can cancel it apparently. Very sneaky design that is disappointing. I had previously declined the offer of a free 90 day trial and had expected that would be the end of it.

    My father has used this app for several months and found it insightful for his sleeping habits, so I decided to start using it. I have found it to be accurate in displaying the graph of how I slept, showing how deep into sleep I was throughout the night. I even discovered some sleep patterns that I didn't know I had just in the few nights I've used it so far. I, personally, am pretty bad about getting up to my alarm, and have found the easy wake feature in this app very useful.

  31. Carla Carla-avatar

    Not sure the price is worth it. However, I LOVE the sleep stories! When I can't quiet my brain, I tune in to The Forest. The narrator has the most soothing voice. I can't find this track anywhere else, so for now I'll keep it. I have used the sleep tracking in the past, and it seems to capture my movements as well.

  32. Fiona McDonald-avatar

    Fiona McDonald


    It was interesting to hear that I snore occasionally! But the app doesn't record my sleep accurately - I was up twice last night with my child and the app didn't detect it. If I choose an alarm window the alarm always goes at the very beginning of the window regardless of how deeply I am sleeping. I got a sleep insight telling me I rise on average at 8.40 despite having been up before 6 every day bar one, when I got up just after 7. So I don't trust the data at all.

    Sleep Cycle has motivated me to get more sleep. I like it a lot. Very basic, not always right about when I'm sleeping, but is what I want. It keeps good records. I like seeing my patterns, and it does that very well. The main reason that I don't give 5 stars is that I can't turn off the alarm. I don't want to be awakened over a time period, and I like my present alarm. I've had to set the alarm in the middle of the day to keep it from disturbing me. Please tell me how to turn it completely off.

    On day 4 of using the app, it needs an option for if you accidentally close app to continue the sleep analysts for that night, if you turn analysis back on it just starts the next day reading automatically, sometimes I wakeup before my wakeup time and do something on my phone real quick and go back to sleep, I have closed the app twise by accident and I feel this causes it to not get the full proper reading. Can my phone vibrating or my cat moving around mess up the reading?

  35. Tiago Levita-avatar

    It first asks for microphone permission and only then shows you the legal notices. On legal notices says they might collect (...) some data you give them voluntarily such as the email address. However, to use the app you are obligated to give the email address so it's not a voluntary thing. When you go to a store, are the prices voluntary? Nope. Are you obligated to buy? Nope. Oh, this isn't a complaint or a ask for help, so no point on answer to this as such. Thanks for your non-answer.

    This app does not work. It doesn't work neither for tracking my sleep nor waking me up at the right time. Sometimes it wakes me up during light sleep, but sometimes it wakes me up in the middle of a dream or at my deepest sleep phase. The app also fails to detect when I wake up in the middle of the night and it tracks the time I'm awake as light sleep and it also sometimes starts tracking my sleep before I have even fall asleep.

    Absolutely wonderful. I dont know how it does it but through sound alone this app is able to accurately tell what stage of sleep you're in. I've only used it two or three times now but each time it has woken me up so smoothly I almost didn't even notice the alarm was going off, and always at exactly the time I wanted to be awake

  39. Test Pro-avatar

    This will drain your battery, so by the time you're supposed to get up for work your phone will be dead, and the alarm won't sound. Avoid. In reply to developers - never had this problem with other similar apps. I suggest you work on the battery consumption, else warn better that it will eat through your battery like crazy.

  40. David Nemati-avatar

    Serves me well, supplying a good estimate of how well I slept each night and helping me keeping track of things I think may affect my sleep. In the past I have used sleep aids, though in recent months I have mostly stopped using them. Great to have multiple modes - I almost always use the simple alarm, set to the time I want to wake up every morning, but occasionally I find it good to wake up within a half-hour range. Some day, it might be good to have a more advanced analysis of things that affect my sleep, taking into account the possible interactions of the factors. But anyone who's not a statistician will prefer what we currently have.

    Good sleep tracker. Would give it 5 stars except alot of the additional features which were free have been changed to premium. Not sure the alarm that is supposed to wake you up when it's the best time during the sleep cycle works, I usually wake up and then it starts going off. I miss my sleep aids, rocks on the beach sucks so now I have to use 2 apps, but over all I think the tracker itself is quite accurate.

  42. Steven Richardson-avatar

    Steven Richardson


    Im giving this 1 star because the app can't be transferred over to android from IOS or vice versa, I bought this app and now because I've changed my phone I can't have full benefits without needing to pay again, tried to resolve this with emails only to be told its not possible, no offer of a code to override that problem and expected to pay again! I don't think so as proof of purchase has been shown, screen shots of lifetime access has been shown and you still won't honour a code to have acces

  43. Andrey A.-avatar

    I have a suggestion - record the temperature during sleep so there could be interesting correlation observed, e.g. sleep quality vs. room temperature. Also the humidity. Many phones have these sensors. Update: it is waking us up when it hears a sound of a car outside every morning. I presume it gets misled because of that. And then, it thinks the quality of sleep is 100% each time we sleep longer than 8h30m which is wrong since we overslept couple of times.

  44. Captain Harlock-avatar

    It performs it's job well. I was a little suspicious about an app that claims to monitor your sleep without doing anything but sit on your nightstand but it seems pretty accurate. And the gentle wake up feature definitely makes getting out of bed in the morning easier.

  45. Nam Karim-avatar

    Nam Karim


    I really like the apps smart alarm. It's great and actually and most other sleep or alarm apps don't have it. However what stopped me from giving this 5 stars is that THERE SHOULD BE AN OPTION THAT ONLY TURNS ON ALARM AND DOES NOT ANALYZE SLEEP. Because keeping ur phone plugged in may damage the battery. I just want the smart alarm. I don't want the app to keep my phone on the whole night. I just want to wake up with the long 30m alarm. PLEASE DEVELOPER S I BEG YOU!! ADD AN OPTION LIKE THIS.

    I do like the alarm feature and feel like it wakes me better than my normal clock. As for the monitoring, its junk. I woke up, left the room, with my phone at midnight and came back and it never registered it. It showed that I was in a deep sleep the whole time. Being able to log when I go to sleep and get up is useful but don't rely on the monitoring.

  48. bitten-avatar



    Annoying how the free trial went through automatically. It's a dark pattern since I they hope you get used to the paid features and then you'll miss them when the trial expires. Also new features come turned on (sleep notes and wake up mood) which is really confusing when your alarm never gets set because you didn't add in your sleep notes even though it was the first time you saw them. The redesign is really nice and the functionality of the app is great though.

    Rubbish. You cannot cancel free trial untill you are forced to pay. They say its a free trial, but you endup paying 30€ because you cannot cancel it through their websote, you cannot cancel it through their app, you cannot cancel it through google play store because technically it is not a subscription yett. Money thieves!

    App overall is good, would get a much higher rating, but I have recently changed my phone and downloaded the app on to my new phone only to discover that a feature I used to rely on on my old phone (the sleep aid feature I rely on it because of my tinnitus) which I paid for when I originally downloaded it, is now a premium feature and I can't get it unless I pay for it forever every month. I have sent them a message asking them to reinstate it for me as I need it, but have as had no reply!

    Great for alarm function with wake-up window. Unfortunately can no make use of statistics. Used to be able to delete short morning naps of say 30 mins, to avoid them affecting the stats. Since update this does no seem to be possible, rather saying this short nap wont affect avg time in bed. All other stats still seems to be affected, giving me very late time going to bed, sleep quality etc etc, making the statistics function useless. Please bring back ability to delete again.

    Great app I used it when I had an iPhone & had to have it when moving across to Samsung. Only thing is Apple you paid a once off fee & Android you have to pay a yearly premium??? At least you can still monitor your sleep. Just can't look over your stat's from other nights.... That's annoying

    It works pretty well. It doesn't always get the cycle right & the alarm will sound when I'm dreaming, but that doesn't happen very often. I'm not sure how someone who needs to wake at a specific time would use this though; I'm retired so it isn't a an issue for me.

    I love this app! My wife is an insomniac and so I learned to sleep on her schedule. Now that I'm trying to get my life in order, this app helps me monitor my sleep quality all throughout the night. It's worth my money since I'm serious about getting my sleep schedule back to normal.

    Surprisingly impressed. So first off for all the people saying "oh my god 30 dollars a year greed blahblahblah". Do you think this app was free and easy to make? Also, thats about 8 cents a night. Pretty much the app listens to when youre in deep sleep and when youre in a light sleep and will wake you up only in a light sleep and you wake up MUCH easier. I was skeptical, but it actually works and im impressed. If you dont think the 8 cents a dsy is worth a good sleep, thats on you my guy.

    First night/morning now, using it and I'm already very impressed. This thing can tell when you're in a light sleep and wakes you up in your time frame accordingly. I've always had trouble waking up but with this I woke up easier than I have in months.

    This is the most simple of sleep trackers and the music and meditation options are always great with a new guided meditation periodically. I also like the option of the alarm to wake me close to my get up time but when I'm in a lighter sleep.

    very good app, would recommend to heavy sleepers, I like that the alarm sound slowly increases and doesnt shock your system like basic alarms do, also it's really cool that you can place your phone on your nightstand and when you want to snooze the alarm you just tap your nightstand twice!!

  60. Tremumbus-avatar



    Missing features. The app is great and gives a useful insight but it has lacklustre features when compared to IOS, examples include smart home integration such as Philips hue and seeing how long you actually slept, not when you went to bed, l dont see the point in not having the sam feature list but I'm not the developer.

    Offers free trial, yet want payment data. Easy scam if you happen to forget to cancel.

    ALARM DOES NOT GO OFF I've had this app for years on iPhone and loved it but upon switching to Android I found that it is dangerously unreliable. The alarm doesn't go off at all. On more than one occasion it's made me late for work or class. I'm really upset that my years of data is essentially useless now.

    I thought I'd give it a shot and try this for a night. I installed it exactly as instructed. I had the absolute wildest night, crazy dreams, woke up 6 times. The app didn't register anything. Zero.

    I am a very deep sleeper and even the noisiest alarms sometimes don't even wake me. I was very skeptical of this because of that, but I saw the reviews and figured I would give it a shot. I had work at 630am so I set the alarm for then. 630 came around and I woke up and looked around wondering why I'm up, then I realized it's because of this alarm that I didnt even hear. I felt so well rested even on 5 and half hours of sleep. Truly amazing what this app can do.

    Only one issue - snore time affects sleep quality a lot. Current quality stats do not reflect that... Would be nice if we can feedback and influence stats so that it means a lot more to individuals with different sleep patterns

    I found the android app does not have all the fields that the ios one has, and I didnt feel its worth subscribing for after my trial period. The free version honestly gives you all you need, and the added few things on the paid android version is definately just not worth the substantial subscription, sorry.

  67. Shikha Dassié-avatar

    Beware the free trial period! They charge automatically for the full year upfront without refunds (or so much as an email confirming subscription!). I didn't find much use for their functionalities. Too cumbersome to use.

  68. Maryam-avatar



    i feel like for as long as i can remember i always woke up feeling sooo tired, then once i saw a youtuber recommend this app so i downloaded it and gave it a try, the next morning i woke up fresh even though i slept at midnight and slept around 3 hours less than i usually do! couldn't shut up about it to my friends and family lol

    Paid for the app a long time ago, but after resetting my phone it's asking me to pay monthly. It seems illegal that you're deciding I need to pay a monthly fee after agreeing to a one-time payment. And even if it is legal, using the app as a smart alarm clock costs you nothing, but you're trying to charge me for "services". You've done the research and made money from me. Stop there. Squeezing me for more money is pathetic.

    I personally think this is a great app. Only tried it for a couple days and so far I'm having some good experiences with it. I always wake up feeling super energetic and ready to work. Awesome! 😁👍

    I like the sound of the alarm (quiet and not startling, I have roommates). And appreciate the ability to keep tabs on my sleep quality.

  72. Liana Quinones-avatar

    Liana Quinones


    I absolutely love the gentle wake up alarm sound. I tend to wake up on a better mood without that abnoucious default alarm sound. It also tracks your sleep time and quality even without the premium feature. I would 10/10 recommend!

  73. Stonerdude Stonerdude-avatar

    Stonerdude Stonerdude


    Brilliant app for me as sometimes I don't know wether I've been asleep or not but this is great! But it's a bit expensive for what it is, but if I had the money I would definitely buy it!!

  74. Austin Munn-avatar

    Austin Munn


    I purchased this app several years ago when it was a one time purchase cost. Now that I have a new phone they will not honor my purchase and are asking for five times the original price per year as a subscription to use the same app I've already purchased.

  75. Y Hu-avatar

    is this app designed to ignore any sound other than what i make? i listen to 40-50min sleep podcast every day. i think i fell asleep pretty soon but based on this app, i don't fall asleep until the podcast is finished. i am a bit confused here.

    Used to be 5 stars, but now it doesn't wake me up as easily as it used to. Now it's just like every other alarm, it's jolts me awake, and is no longer the gentle experience it used to be. Cancelled subscription and deleted.

    I have no idea why, but when I keep going back to my "about me" setting it keeps switching to the minimum weight and maximum height. UPDATE: The issue has since been resolved. Changed to five stars.

    I actually really like this ap but cancelled just before my free 30 day trial was due to expire. Hope i managed to cancel!? Hard to know if my cancellation was successful. Has anyone else had this problem? Many thanks sleep cycle ab for your reply. I have contacted support direct for help with refund. Best wishes to you too.

  81. Kate Martin-avatar

    Have been using this app for years to monitor my sleep patterns through curiosity and when I feel tired I check my sleep pattern and it always correlates to a low percentage. So I'd say this app is pretty accurate!

    I really liked it, I would have liked to be able to modify the going to sleep and awakening times because I don't always wake up when I turn off the alarm.

  83. Luke Harvey-Palmer-avatar

    A good app, that appears more accurate than others. However, some of the essential features are premium, and the price for premium is too high I believe.

    Pretty good app. It wants you to buy a lot of stuff but wakes you up at the right moment and can sense your movement really good even with a fan going at night.

    It has help to improve my sleeping habits. Before discovering the app and going premium, I was struggling to develop and maintain a good sleep hygiene.

    Gives a great detail of sleeping time and habits. Love the time frame as well showing when you have been awake or in deep sleep. This app is very easy to use.

  89. S Mosley-avatar

    I give three stars because you really should say the app cost money to use, otherwise you only have access to one feature. Also should note, the price is yearly fee not one time fee.

    Hi I really like this app, atm I have a free premium trial which ends in 5 days, the app is not on my google play subscriptions so I don't know how to cancel my free trial as I really can't afford to pay for a subscription, any help would be appreciated

    Heaven Harris


    So far I love it I think it's really cool and it's on point with my sleeping and I think it's great that it can tell when I'm awake and when I was in a deep sleep and if I snored (I dont snore😂) all in all it's a great app so far.

  99. Jennifer Vink-avatar

    No explanation of how the "analysis" is determined. Spotty results IMO. Also no reminder that you are about to be charged $29.99. I thought I had one more day. Now I have to hassle with my credit card company to get a refund.

  104. Armuotas-avatar



    I give it one star for a simple reason that I did not / will not try it. It is because "no, I will not create an account to keep my data safe accross the devices" and I will not login with Google as a matter of principle. So there you go.

    The app automatically charges a yearly subscription fee after the trial ends. This is unexpected. I don't like it.

    Not able to try its features, simply it asked me to subscribe. 7 day free trial is an eye wash, because it says minimum 4 days data needed to show the analysis and the analysis also ask me to buy....Just a waste of time and effort.
